Part of the draw is the unique range of offerings. There's a waiting list of 600 customers for the Goose Creek heirloom tomato plants and brisk demand for -- as Jimmy Williams tells it -- descendants of the mint plant Bob Marley used to brew tea on his porch in Jamaica.
Williams' help in building a garden can run from hundreds of dollars to a few thousand dollars, depending on how much the soil needs to be enhanced with ingredients such as potting soil, alfalfa and chicken manure. It's an expertise customers seem to trust.
